The displacement of patellar components, such as dislocation or subluxation, causes polyethylene wear and further induces metallosis of the metal-backed patella. We compared two different patellar components, onset(Miller-Galante I) and inset(Whiteside-Ortholoc I)type, to understand the differences in patellar tracking according to their designs. Patellar prosthesis position in 43 primary total knee arthroplasties was evaluated with patellar tilt, patellar displacement from the center of the trochlear groove, medial placement, patellar thickness, and joint line height. For the MG(Miller-Galante I)group, the patellar displacement was laterally 50.0% and for the Ortholoc group, it was 33.3%. In the MG group, 4 cases of revision of the patellar component due to excessive polyethylene wear were performed, but there was no excessive wear of polyethylene in Ortholoc group. One of the primary factors which influence tracking of the patellofemoral joint is the difference in design between the patellar component and the femoral component. But in the opinion of the authors, the slope or lateral displacement of the patellar component have no correlation with each other under radiological measurements. However, the inset-type patellar component is a design that maintains the bony flange within the lateral flange, therefore relieving the shear stress and rotational forces loaded on the patellofemoral joint and protecting the metal-backing from exposure. Thereby, even if dislocation or subluxation of the patellar component should occur, polyethylene wear or metallosis caused by excessive wearing can be minimal.

PURPOSE: The purpose of this study is to examine the factors influencing the barriers faced by Korean nurses in addressing the patients' sexual health. METHODS: The subjects in this study were nurses working at hospitals in Seoul and Jeonju. The data for this study were collected between November 2008 and December 2008. The subjects were assured of anonymity and confidentiality. RESULTS: The barriers to addressing the patients' sexual health were moderate in the subjects. The nurses had moderate sexual knowledge and communication skills. In a stepwise regression analysis, the areas of work, communication skills, participation in sexual health training, and experience in Obstetrics and Gynecology accounted for 18.3% of the variance of the barrier for addressing the patients' sexual health. CONCLUSION: These findings emphasize the need for the development of a patient-centered sexual health-related curriculum for nurses, which has been briefly discussed in Korea. An educational program that improves the nurses' communication skills will be effective in reducing the barriers to addressing the patients' sexual health and will help the nurses become sexual health specialists.

PURPOSE: The purpose of this research wasto examine the relationships between gender role attitudes and barriers in Korean nurses when addressing patients' sexual health. METHOD: The sample for this study was a convenience sample of Korean nurses who worked in hospitals in Seoul and Jeonju. Data were collected between November 2008 and January 2009. RESULTS: Nurses showed less traditional gender role attitudes with means score of 40.72 (SD=3.99) of a possible 10 to 50 range. The barriers to addressing patients' sexual health were moderate in these nurses with a mean score of 44.92 (SD=7.66) of a possible 12 to 60 range. There were significant correlations between gender role attitudes and barriers to addressing patients' sexual health (r= -.142, p= .007). Nurses with less traditional gender role attitudes felt more barriers to addressing patients' sexual health. CONCLUSION: This study demonstrates a need for educational programs that will improve the problem-solving abilities of nurses in a hospital environment and help them gain ground as sexual health specialists. The results may contribute to the development and application of a patient-centered sexual health-related curriculum, which would aid nurses in addressing sexual concerns of their patients.

PURPOSE: The purpose of this study was to develop and validate the Sexual Health Care Scale-Practice (SHCS-P) for oncology nurses to use in nursing care. METHODS: Apreliminary version of the SHCS-P of 32 items was developed based on the literature and opinion of experts. A panel of eight experts reviewed the preliminary questionnaire for content validity and consolidated the instrument, which was, then, tested with data from 342 oncology nurses in Korea. RESULTS: Exploratory factor analysis showed that the SHCS-P explained 70.49% of the total variance. The instrument revealed four factors that were named: (1) Practice for sexual function (8 items), (2) Practice for psychological factors (6 items), (3) Practice for social problems and records (4 items), and (4) Practice for reproductive care (3 items). Internal consistency was good, asassessed by the KR 20 value of 0.91. The coefficients for the sub-factors were between 0.81 and 0.93. CONCLUSION: This scale shows validity and reliability in evaluating the practice of oncology nurses in providing sexual health care and can be used to evaluate the level of practice well as test effects of educational interventions to improve sexual health care competency.

PURPOSE: The purpose of this study was to identify cultural competence and factors influencing cultural competence of nursing students in South Korea. METHODS: Participants in this study were 248 nursing students who agreed to participate in the study. Data were collected during November and December, 2012 using structured questionnaires. Data were analyzed using PASW/WIN 20.0 program and included t-test, one-way ANOVA, Scheffe test, and multiple regression. RESULTS: The mean score for cultural competence in nursing students was 3.0 points out of a possible 5. Factors influencing cultural competence in nursing students were identified as being female (beta=-.23), third year (beta=.30), having foreign friends (beta=.29) and fluency (beta=.12). These factors explained 18% of cultural competence reported by nursing students (F=10.13, p<.001). CONCLUSION: The results of this study show the major factors influencing cultural competence in nursing students. Therefore, it is recommended that further cultural competence promotion programs for nursing students be considered directly along with ongoing transcultural experiences.

PURPOSE: This descriptive study was done to develop a predictive model of depression in rural elders that will guide prevention and reduction of depression in elders. METHODS: A cross-sectional descriptive survey was done using face-to-face private interviews. Participants included in the final analysis were 461 elders (aged> or = 65 years). The questions were on depression, personal and environmental factors, body functions and structures, activity and participation. Decision tree analysis using the SPSS Modeler 14.1 program was applied to build an optimum and significant predictive model to predict depression in rural elders. RESULTS: From the data analysis, the predictive model for factors related to depression in rural elders presented with 4 path-ways. Predictive factors included exercise capacity, self-esteem, farming, social activity, cognitive function, and gender. The accuracy of the model was 83.7%, error rate 16.3%, sensitivity 63.3%, and specificity 93.6%. CONCLUSION: The results of this study can be used as a theoretical basis for developing a systematic knowledge system for nursing and for developing a protocol that prevents depression in elders living in rural areas, thereby contributing to advanced depression prevention for elders.

PURPOSE: The purpose of this study was to investigate the balance confidence and balance ability among community-residing stroke patients. METHODS: The sample for this study was a convenience sample obtained from patients who visited welfare centers for the disabled in three cities from October to December in 2009. The Activities-specific Balance Confidence Scale and Berg Balance Scale were used to measure confidence in task performance and balance ability. RESULTS: The level of balance confidence and balance ability were low in these subjects. There was a significant relationship between balance confidence and balance ability (r=.424, p=.000). Subjects with less balance ability felt less balance confidence. CONCLUSION: Among community-residing stroke patients, falls are common. Falls prevention which may contribute to the incidence of fall and fall related injury should be part of stroke rehabilitation plan. Also, it is necessary that an intervention for falls prevention after stroke should take into account factors such as the balance confidence and balance ability.

PURPOSE: This study was done to identify the level of Internet addiction among adolescents, and to examine factors affecting Internet addiction in adolescents. METHOD: The participants in were 475 high school students. Data were analyzed using multiple regression analysis to examine the factors affecting Internet addiction in adolescents. RESULT: The overall Internet addiction scale score was 63.83(+/-20.48). The differences of Internet addiction according to student characteristics were found to be significant for sex and grade. The level of Internet addiction was positively related to the level of impulsiveness and depression. The level of Internet addiction was negatively related to the level of social support. Factors such as impulsiveness and social support were examined as significant factors predicting Internet addiction in adolescents. CONCLUSION: Based upon these findings, factors affecting Internet addiction in adolescents include impulsiveness and social support. The findings provide further justification for interventions targeting key factors that influence Internet addiction in adolescents in addition to providing adolescents with necessary communication, negotiation and other life skills.

PURPOSE: This study was performed to explore the effect of senior simulation on nurses' attitudes toward the elderly. METHOD: Twenty-seven nurses working in various settings such as acute hospitals, community health centers, geriatric hospitals, and clinics were recruited. Among them, 25 subjects completed the whole experimental protocol. Aging Semantic Differential Scaling was utilized to evaluate attitudes toward the elderly and 'Suit for Experiencing Being Aged' from the Sakamoto Model was provided for the experiment. Before and after the experiment subjects filled out questionnaires. RESULT: Attitude score before experiment was 4.36, which indicates neutral attitude. Objective attitude scores were not different significantly after experiment. However subjective statements indicated attitude changes in a positive way. CONCLUSION: Senior simulation can affect nurses' attitude toward elderly in subjective way. That is, nurses became more empathetic and understanding to elderly's physical limitations and felt more initiative nursing approach were needed in caring elderly.

These experiments were performed to investigate the effect of saline, melatonin, stress, stressed-melatonin on serotonin immunoreactivity in rat brain stem. The animals were injected with melatonin (1 mg/kg, i.p.) after electric shocks for 15days. The results were as follows; 1. Serotonin immunoreactive neurons in brain stem (the number of staining neuron & the stain intensity in dorsal raphe nucleus of midbrain, the stain intensity in nucleus tractus solitarius and dorsal raphe nucleus of vagus nerve in medulla oblongata) were decreased in melatonin treated group compared with all the other groups. 2. Serotonin immunoreactive neurons in brain stem (the number of staining neuron & the stain intensity in dorsal raphe nucleus of midbrain, the stain intensity in nucleus tractus solitarius and dorsal raphe nucleus of vagus nerve in medulla oblongata) were significantly increased in stressed group compared with all the other groups. 3. Serotonin immunoreactive neurons in brain stem(the number of staining neuron & the stain intensity in dorsal raphe nucleus of midbrain, the stain intensity in nucleus tractus solitarius and dorsal raphe nucleus of vagus nerve in medulla oblongata) were significantly decreased in stressed-melatonin treated group compared with only stressed group but were significantly increased compared with melatonin treated group. These experiments indicate that serotonin immunoreactive neurons in dorsal raphe nucleus of midbrain were increased, due to the activation of stress, and decreased when the activating of stress is suppressed through melatonin treatment.
